Investor interest is driven by the growth pace in the domestic airline
market, one of the fastest in Asia.

Vietnam has over the past years been slowly opening up to international
investment.

VietJet currently operates about 60 routes both domestically and
internationally, and hopes to have a fleet of 200 aircraft by 2023.

The budget airline is another story of a booming Asian low-cost carrier
managing to clock exceptional growth in its first years since taking to the
sky.

The airline launched its first commercial flights only in December 2011 but,
thanks to a rapidly growing middle class, has jumped to become the country's
second-largest airline, almost head to head with flag carrier Vietnam
Airlines.

Both carriers have about 40% of market share. But if Vietjet's past growth
is anything to go by, it is set to claim the top spot in no time.

While most analysts agree that the domestic market will continue to show
strong growth, there is caution over whether Vietjet will be able to replicate
that success abroad.

"There's no doubt that they are the dominant low-cost carrier in Vietnam,"
explains aviation analyst Greg Waldron of FlightGlobal. "The question is
whether they can really expand that model overseas."

"These business models are not like McDonald's, where you can just replicate
the model elsewhere," he explains.

"With airlines, it's a lot more challenging: if they go internationally,
this would add a huge amount of complexity to their business model. Long-haul
flights would again be a completely different game."

Aside from its impressive growth rates, the airline is also known for its
somewhat controversial PR stunts.

In the past, the airline has made occasional headlines with PR stunts of
having its stewardesses serving the aisles wearing little more than a bikini as
uniform.

"They've been clever about their marketing," says Mr Waldron. "This gave
them huge publicity all over the world."

There's little doubt it garnered global coverage. In case it strikes you as
somewhat inappropriate, however, Vietnamese authorities agree.

In at least one of the instances, Vietjet was fined for hiring models for an
on-board bikini show.
